Original length of the rope = 4m

Size of each piece = 3/5 m.

No of cords of same size formed will be

4 \div \frac{3}{5} \\ = 4 \times \frac{5}{3} \\ = \frac{20}{3} \\ = 6 \frac{2}{3}

Therefore \: the \: person \: will \: make \: \: 6 \frac{2}{3 \: } cords.

What is an equation of the line that passes through the points (0, -2) and (0,-5)?
choli [55]

Answer:

x = 0

Step-by-step explanation:

We can find slope using this formula:

\frac{y2 - y1}{x2 - x1} = slope

So we plug it in like this:

\frac{-5 - -2}{0-0} = \frac{-3}{0} \\

We see that the slope is undefined so it will be a straight vertical line

So in order to pass through y = -5 and y = -2, x would have to equal 0.

Therefore, the equation is x = 0

<em>Hope this helps!!</em>

Which answer describes the type of sequence? 200, 40, 8, 1.6, ...
GalinKa [24]

Answer:

Option 1  the given sequence is a geometric.

Step-by-step explanation:

We have been given with the series

200,40,8,1.6

Arithmetic sequence is the sequence in which difference between consecutive terms is same that is common difference d

d=a_2-a_1

d=40-200=-160   herea_2=40,a_1=200

d=8-40=-32          herea_2=8,a_1=40

We can see the difference is not same

Hence, the given sequence is not arithmetic sequence.


Geometric sequence is the sequence in which ratio of consecutive terms is same that is common ratio r

r=\frac{a_2}{a_1}

r=\frac{40}{200}=\frac{1}{5}   herea_2=40,a_1=200

r=\frac{8}{40}=\frac{1}{5}          herea_2=8,a_1=40

r=\frac{1.6}{8}=\frac{1}{5}             herea_2=1.6,a_1=8

We can see the ratio is  same.

Hence, given sequence is geometric

Therefore, Option 1 is correct given sequence is geometric.

$1689 invested for 4 years at 3% compounded annually ?
Ira Lisetskai [31]

The amount gotten after $1689 invested for 4 years at 3% compounded annually is $1901

The amount of money gained after an investment is compounded is given by:

A=P(1+\frac{r}{n} )^{nt}

Where P is principal, A is the final amount, r is the rate, n is the number of times compounded per period and t is the time

Given that P = $1689, t = 4, r = 3% = 0.03, n = 1, hence:

A=P(1+\frac{r}{n} )^{nt}\\\\A=1689(1+\frac{0.03}{1} )^{4*1}\\\\A=\$1901

The amount gotten after $1689 invested for 4 years at 3% compounded annually is $1901
